Hemodynamic findings in patients with brain stroke
Archives of Medical Science, 05/18/2012
Siebert J et al. – The hemodynamic parameters correlate with long term prognosis in patients with ischemic brain stroke.Methods
- The 45 consecutive subjects with ischemic stroke and 16 with a hemorrhagic stroke were examined additionally with impedance cardiography during the first day of hospitalization.
- The heart contractility, pump performance, afterload and preload indices were recorded and calculated automatically and the data analyzed in terms of 6–month mortality.
- The authors found a significant association between the systemic vascular resistance index, Heather index, stroke index, heart rate, systolic and diastolic and mean arterial blood pressure and mortality in patients with ischemic stroke (p = 0.002, p = 0.008, p = 0.012, p = 0.005, p = 0.007, p = 0.009, p = 0.002 respectively).
- Logistic regression analysis identified the thoracic fluid content as the most significant variable correlating with the non–survival of the patients with ischemic stroke and in the whole group (ischemic and hemorrhagic stroke).
- The significant parameters were also mean arterial pressure and stroke index in ischemic stroke (the correct answer ratio was 86.67%) and heart rate in the whole group (the correct answer ratio was 80.33%).
- There were no significant associations in hemorrhagic stroke.
